Here I share with you the analysis regarding champions costing 20 Sacred Shards during a Guaranteed Event in RAID to help you decide:
As noted, the conclusion is:
- At the cost of 20 Sacred Shards the Guaranteed event is no longer statistically effective - a regular x2 is better.
- Exception: unless the Guaranteed champion is very wanted by you.
- While pulling shards may result in a random champion (is RNG), it is the only way to pull the BEST champions in RAID as few players expect Plarium to give the best champions like Duchess in a Guaranteed Event.
